To all whom it may concern..- 7

Be it known that I, HENRY D. BABoooK, of Leonardsville, in the county ofMadison and 'State of New York, have invented certain new and usefulImprovements in Harrows; and I do hereby declare that the following is afull, clear, and exactdescription of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters'and figures of reference marked thereon, which form part of thisspecification.

My invention relates to improvements in barrows.

In the drawings which accompany and form a part of this specificationand in which similar letters and figures of reference refer tocorresponding parts in the several views, Figure 1 shows a partial planview of my harrow. Fig. 2 shows a side elevation of one section of theharrow from the inner or hinged side. Figs. 3, 3% and 3 show details ofthe bearing of the front rocking cross-bar and the eye to which thedraft-links are attached. Figs. 4 and 4 show details of the connectionbetween the forward ends of the draft-bars of the frame. Figs. 5 and 5Show details of the front hinge between the sections of the harrow.Figs. 6 and 6 show details of the rear hinge between the sections of theharrow. Fig. 7 shows details of the bearing of the end of one of therocking cross-bars, whereby it is suspended below the frame-bar. Figs. 8and 8 show details of the bearing or mounting of the rocking cross-barwhere it is supported above the" frame-bar. Fig. 9 shows a bearing inwhich the rocking cross-bar is supported where the cross-bar extendsbeyond the frame-bar to support a tooth on its end. Fig. 10 showsfurther details of the bearing shown in Fig. 9. Fig. 11 shows detailsofthe tooth-holding device. Fig. 12 shows details of the toothholdingclip.

The harrow consists of two sections A and B, each section being composedof an outside draft-bar l and an inside draft-bar 2, extending from therear of the frame to the front and bent together at their front ends,form- 5o ing a nose, the two front ends being securely held together bya nose-piece 3, which conforms in shape to the angle-iron of which thedraft-bars are preferably made, and is bolted or riveted to each. Thenose portion 0 of the section is inclined upwardly from the plane of theharrow from a point about even with the front rocking cross-bar. Theoutside draft or frame bar 1 is extended from the front in the plane ofthe harrow-frame, while the inside frame-bar 2 is provided with anuprear portion of this bar considerably above the plane of the undersurface of the harrow. The bend 2 in the inner frame-bar is preferablyprovided between the front rocking crossbar 4 and a second rockingcross-bar 5 from the front.

On the under face of the forward portion of the bar 2 is provided awearing shoe or piece 8, adapted to run on the surface of the ground andgage the depth of out of the tooth, and at the same time protect theharroW-frame at this point from wear. The forward end of the frame-bar 1may also be provided with such a wearing plate or shoe.

The front rocking cross-bar4 is mounted in eyes 6 of the bearing-pieces7, secured on the front portion of the section. These bearingpieoes arealso provided with eyes 8, in which engage-the draft-links 9, extendingto and attached to the evener 10. The rocking crossbar 5 is mounted atone end on the outside frame-bar 1 by having its end engage in thecircular opening or eye of the bearing-piece 11, secured on the uppersurface of the bar l.

To prevent endwise displacement and to also furnish a supportingconnection between the frame-bars l and 2, there is on the rockingcross-bar 5 a hook-like clipping-piece 12, which is secured to the barby a bolt 13 and is provided with a shoulder 12, adapted to engage onone side of the bearing 11, and a shoulder 12 adapted to engage on theother side. The inner end of the bar 5 is supported on the under side ofthe frame-bar 2 by a suspending bearing-piece 14 similar to 11, and thebearing is also held in engagement with this bearing by a hook-like clip15 similar to 12 and similarly applied, except that it is in an invertedposition 'from that illustrated in Fig. 8. The rear rocking cross-bar 16is supported at its outer end in the same ward bend, as shown at 2,which brings the manner, as illustrated in Figs. 8 and 8, with referenceto cross-bar 5, and its inner end is extended or projected, so as toform a mounting fora tooth between the two sections of the harrow. Thereis a special bearing 17 pro-,

vided for this bar on the rear end of the framebar 2. On the bar 16 issecured a collar 18 by means of a rivet 19 passing through the collarand the web of the cross-bar 16, the interior of the collar 18 beingadapted to receive and hold the eye-shaped cross-bar 16. The collar 18is partially received within the eye of the bearing 17, and is providedwith a shoulder 18, which engages against the side of the bearing-piece17 and secures a connection between the frame-bars 1 and 2 to preventlateral displacement or springing.

The teeth a a are suitably placed over the several rocking cross-barsto' most effectively do their Work and cover the entire surface overwhich the harrow may be drawn and are secured on the cross-bars by aclip 20. The teeth are supported on the edges or walls of the eye-ironof which the cross-bars are formed. The clip is provided with cars 2020, which are so disposed as to be received between the heads of theeye-iron and also form walls for the lateral edges of the teeth toprevent lateral displacement or twisting in the clip. The clip is heldto the cross-bar by bolts 21 passing through the holes 20 in the clipand holes in the web of'the crossbar. The width of the body of the clip20 is less than the distance between the walls of the eye-iron on whichthe tooth is held, so that it is held under spring tension, thus0bviating any tendency to work loose, and the tooth is adjustable on itsseat by loosening the bolts which hold the clip and sliding it throughunder the clip.

On the middle of each of the rocking crossbars 4, 5, and 16 is securedan upright post I), and extending from front to rear and pivoted to theupper end of each of these posts is a connecting-rod c, by means ofwhich the several rocking tooth-bars of each section may besimultaneously moved. The rear post I) is extended, forming alever-handle L,

which is provided with a springactuated catch d, adapted to engage in asemicircular rack e on the rear end of the bar 0 and secure the rockingbars and the teeth thereon in any of their adjusted positions. Suitablemeans are also provided for operating the catch d.

I The sections of harrow are hinged together by the front hinges 22 andrear hinges 23 engaging each other from the opposite sections of harrowand being formed substantiallyas shown in Figs. 5 and 5 for the fronthinge and Figs. 6 and 6 for the rear hinge, whereby the eyes of thefront and rear hinges'are brought into the same line. The hinges areprovided with pintles 24 and 24.

By the construction of frame herein shown, with the outer draft-bar ofeach section of the frame lying substantially in the plane of the undersurface of the harrow and the section of the frame being pointed at thefront, any clods or debris with which the harrow comes in contact on theouter side of the middle line of each section is passed outward andaround the harrow as it is at work. By the bend or deflection of therear portion of the middle frame-bars to a higher planethan that of theunder surface of the harrow a clearance is given in the middle of theharrow, so that any clods or obstructions to the harrow may be readilycleared and not be carried or dragged along by the frame, thus cloggingthe harrow and reducing its efficiency.

By the arrangement of bearings and clips hereinbefore described thedraft-bars are securely stayed and held by the rocking crossbars withoutthe use of additional pieces or parts for this purpose and the weightand expense of the harrow-frame are reduced to the minimum.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a sectional harrow the following ele ments in combination:draft-bars parallel in portions of their length deflectedupwardly attheir front ends; a wearing or reinforcing shoe conforming to the angleof the draft-bars; turnable tooth-bars and lever-operating mechanism forthe purposes stated.

2. In a sectional harrow the following elements in combination: paralleldraft-bars in portions of their length; turnable tooth-bars atsubstantially right angles to the draftbars; tooth-bar sockets or clipssecured at one end to the draft-bars and provided with tooth-bar socketsat their free ends and arms carried by the tooth-bars and overlappingsaid clips for holding the tooth-bars from end thrust, and levermechanism for operating the turnable tooth-bars as set forth.

3. The combination in a harrow, of turnable tooth-bars, draftbars orrunners integral in their length, the inner draft-bars deflected attheir rear into a plane above the other portions of the draft bars orrunners, substantially as described.

4. In a harrow, the combination of turnable tooth-bars, draft-barsprovided with tooth-bar sockets rigidly secured thereto, and clipssecured to the tooth-bars and arranged to overlap portions of thetooth-bar sockets on the outer sides thereof, substantially asdescribed.

5. In a metal-frame harrow, the combination of draft-bars parallel inportions of their length'and deflected at their front into engagementwith a nose-piece to which they are rigidly secured, and the nose-piece,substantially as described.

In witness whereof I have affixed my signature in presence of twowitnesses.
